Adding location and audio setup to user profiles

Hi, would be great if people could add their location and/or audio setup to their user profiles. Will be helpful when we're interacting to know where you're from and what kind of setup you have. Thanks!
You mean aside from the “mini into some other, bigger stuff” I see on your comments?
Oh, you can see that, can you! I can't, so no idea others could.
Maybe I'll make it less flippant... ;)

Is it maybe a setting I've not enabled somewhere? I don't see any such comments on anyone's posts, so either no one else has a signature or I've disabled seeing them somehow.
